Answer 1

$1)y=15x^2-4x-7 \ 2)y=2- frac{1}{2 sqrt{x} } +15x^2+ frac{1}{x^2} \ 3)y=2*(x^2+3x-1) + (2x+3)*(2x+1) = 6x^2+14x+1 \ 4)y=e^x*(x^2+x-1)+e^x*(2x+1)= x*e^x(x+3) \ 5)y= frac{3x^2(x^3-2)-3x^2(x^3+2)}{(x^3-2)^2} = frac{-12x^2}{(x^3-2)^2}$

$6)y=5x^4+ frac{2}{x} \ 7)y= frac{3^xln3e^x-3^xe^x}{e^2x} = frac{3^x(ln3-1)}{e^x} = frac{3^x(ln3-lne)}{e^x} = frac{3^x(ln frac{3}{e} )}{e^x} \ 8)y=- frac{1}{ sqrt{1-x^2} } - frac{3}{ sqrt{1-x^2} } = frac{-4}{ sqrt{1-x^2} } \ 9)y=2cosx+3sinx \ 10)y= - frac{1}{sin^2x}$
